The default regulator names in ST7701 chip is renamed in Techstar TS8550B so, add specific binding names for them. Signed-off-by: Jagan Teki --- Changes for v5: - found the chip from vendor, so added new chip binding - here is v4: https://patchwork.kernel.org/patch/10680333/ .../display/panel/sitronix,st7701.txt | 30 +++++++++++++++++++ 1 file changed, 30 insertions(+) create mode 100644 Documentation/devicetree/bindings/display/panel/sitronix,st7701.txt diff --git a/Documentation/devicetree/bindings/display/panel/sitronix,st7701.txt b/Documentation/devicetree/bindings/display/panel/sitronix,st7701.txt new file mode 100644 index 000000000000..ccd17597f1f6 --- /dev/null +++ b/Documentation/devicetree/bindings/display/panel/sitronix,st7701.txt @@ -0,0 +1,30 @@ +Sitronix ST7701 based LCD panels + +ST7701 designed for small and medium sizes of TFT LCD display, is +capable of supporting up to 480RGBX864 in resolution.
